When it comes to the characterization of fiber reinforced composites with dynamic measuring techniques many options are available, but they all have pros and cons for different materials and applications. In their paper, Huayamares et al. set out to answer some relevant questions by comparing measurements in 3-point bending and torsion mode. We summarize the main findings of the scientific paper and explain the measurements as well as the corresponding interpretation of the results depending on the use case.
Thermogravimetry (TGA) is frequently applied for the compositional analyses of such materials as, for example, fiber-reinforced polymer composites. The residual mass at the end of a TGA experiment reflects the filler or glass fiber content as well as the presence of impurities. By using a relatively large sample volume in a top-performing thermobalance along with the intelligent Proteus® software by NETZSCH, it is possible to detect ultra-small residual masses with concentrations down to the ppm (= 10-6) range! Such small concentrations can be illustrated by a little bird with a mass of a few grams sitting on the back of an elephant weighing a few tons.
The Kinetics Neo software by NETZSCH allows for advanced analytics. Learn how to predict the decomposition behavior of materials under different climatic conditions and how to estimate thermal risks and hazards.
During 16th ICTAC, it was decided to develop recommendations for the kinetic analysis of multi-step reactions. NETZSCH Analyzing & Testing is the only enterprise specialized in the development and production of commercial kinetics software that was invited to participate in this project to develop these recommendations. We are proud to announce that the recommendations are now available!
The NETZSCH Kinetics Neo software is used for the analysis of chemical processes. It enables analysis of temperature-dependent processes. The result of such analysis is a kinetics model or method that correctly describes experimental data under various temperature conditions. Get an overview and watch the video to find out how it works!

Polymer blends offer significant advantages during their service life. However, they make recycling at the end of life difficult. One of the most fundamental problems is the identification of the material as a blend as well as its composition to ensure it is sorted properly and can be reused if possible. Read how to TGA and FT-IR help with the identification and join our webinar series on TG-FT-IR!
In the previous articles, focusing on thermal analysis under humidity, we have seen that thermogravimetric analysis and dynamic mechanical analysis help determine the influence of water on a material or substance. Thermomechanical analysis complements the analysis under humidity.
Water is one of the major parts influencing our climate. Our atmosphere is filled with water. We may not always be able to see it, but it interacts with us and our materials. Learn how thermal analysis helps identify water absorption and determine water content.
Sporting goods and toys for kids or pets are often made of flexible plastics. Some examples are sensory chewing toys, action figurines as well as balls of various kinds. A common polymer used for these applications is PVC (polyvinylchloride), because it can be made softer and more flexible by adding plasticizers. Therefore, they can evaporate or be rinsed out by saliva or sweat. Learn how to determine detect and identify plasticizers!
